All modern regs are interchangeable. There were some older ones that weren't, but most should be past their lifespan or rapidly approaching it.

any screw in tank regs are easily interchangeable. if you have a PE and want to switch to a Ninja, or something like that, then unscrew and screw.

This, but also to add (which no-one else has brought up) it is possible to put a 3k reg on a 4500 tank- Don't do that, it's bad. Always make sure the tank matches the reg pressure, If you must mix and match in a pinch, never overfill your lowest rating, and never let someone who is not yourself fill that tank.

Switch that. Ok to put 3k on a 4500 tank. Don't put a 4500 reg on a 3k rated tank.

I think the best statement there is to add not to put more than 3k of pressure into that tank.

Whoever is filling the tank should be checking the reg. All regs are marked with max PSI.

better said: put a 3K reg on a 3K tank and a 4.5K reg on a 4.5 tank. don't try to mix and match. that can be an accident waiting to happen.

I have a couple of questions to add: I have an old Nitro Duck tank with an adjustable reg, it's the one that used the ring cradle 92 ci x 3000 psi I think. The tank is past it's 15 year life so I'm wondering if there is a new same size tank out there I could get to use with reg from the old tank. If not I also have an old Max Flo reg ( not the one that screws into the bottle but the bottle screws into it like an on off Asa) the reg is low pressure and I want to convert it to high pressure... How?

2 different questions have two different answers...

the bad thing that NitroDuck tanks have is that PMS/Nitroduck used a different threading from other companies that produced HPA tanks. its 5/8ths where the world is 3/4ths or vice versa. so you may or may not be able to find a tank in hydro for that reg.

i am not hugely familiar with the old Maxflos but i do know that you would have to change the main spring pack to go from low pressure to high. now, the bigger question is finding an HP spring pack for replacement. i'd look at I&I and some of the older stores that collected older parts like that.

The spring that is in it now is pretty stiff but it has a low pressure gauge on it. I guess the High pressure spring is even stiffer ?

Flatliner333:

Its not just a spring that is needed. The smart parts manifold style regulators need a different manifold body and piston as well in order to change from low pressure to high pressure. The newer inline regulators needed just the front section that screwed into the manifold body and also the high pressure piston and spring, which made the change a bit easier and less expensive.

The original manifold style regulators used unregulated bottles with left hand threads. The newer manifold style regulators used regulated bottles with standard ASA threads.
